Thank you. I ended up getting the Restricted Social 147. I asked for the 147, but the people at the snowboard store recommended I get the 142 since I was a beginner. My husband and I said OK to their recommendations, then they opened and put my bindings on a 147. I think I'll just stick with it.
Thank you to everyone for your help and suggestions.
Good luck! Weight range is the most critical spec of a board while you're shopping, and then you tailor the length based on ability, muscle, what you plan to do with the board, etc.
As a beginner it's always best starting in the middle of the weight/flex/size ranges. Sounds like you got something that should work fine for you...
